Hey
I have an A-5, Stock except for Java expansion chamber (I am using CO2, and no, i am not going to compressed air), and my upcoming paintball game is going to be cold, like something around 15 degrees give or take with snow. I haven't played in this cold since i got it and would like to call on any ideas (like where to place hand warmer packs, will it help, ect.) on how to make it not malfunction, or worse, me damage it, in this cold weather.
